YES! You should periodically check for and update to the latest version using the program’s internal update function in the top menu to stay current with the latest methodology in preventing this (and other) malware. After update it is then necessary to re-apply the protection to your system. It is not necessary to undo the previous protection in place before doing this, or even to uninstall the app before updating. If you have an older version of the app before the update functionality was introduced, simply download and install the latest version, then re-apply protection.
This process is entirely automatic for users of the Automatic Update edition.
